A method is described for detecting an object with radar. After the first detection of an object, the antenna is tilted. The original direction towards the object is restored by electronically steering the emitted beam. The beamsteering is obtained by changing the frequency of the emitted signal. Thus, the object may be detected several times on different frequencies. The method is particularly applicable in search and track radars.

Cette invention se rapporte à un procédé de détection d'un objet au moyen d'un radar. A cet effet, après la première détection de l'objet, l'antenne est inclinée. La direction d'origine de l'objet est rétablie par guidage électronique du faisceau émis. Le guidage du faisceau est obtenu par modification de la fréquence du signal émis. Ainsi, l'objet peut être détecté plusieurs fois sur des fréquences différentes. Ce procédé peut s'appliquer en particulier dans des radars de recherche et de poursuite.
